Where can I delete an document
If I don't need a document any more, how can I delete it?
Go onto your Onedrive, go into documents, select the document and delete
sorry I can not help you with that as I am in the same situation! :-(
All I can say is you can ask some computer specialist.
I hope your situation n gets solved! :-)
As Katie Zhou commented, it's easy enough to delete -- the catch (for me) is that you first have to locate the nearly invisible point in the upper right corner of your document thumbnail before you can click there and activate the menu that includes Delete as one possible action. Click this, and you're done. (You even have a chance to Undo your action if you realize right away that you deleted the wrong document.)
My only issue with this (besides the challenge of spotting where to click) is that there doesn't seem to be a way to delete a document once you've opened it. I typically realize I want to delete a document AFTER i've opened it. Because many of my documents look pretty similar in their thumbnail forms, I end up opening one document after another until I find the one I want to get rid of. Then after I've closed it, I have to remember its name so I can make sure I'm deleting the correct file.
Guess I should post that as a separate comment....
